Urahara opens the gate, and our heros jump through, after making sure Urahara will attend to Ichigo's family. Ichigo also resolves to apologize to his friends, which is a good thing to have said, considering they followed him inside. Urahara, being more or less omniscient at the moment, of course knew all along that they'd sneak in. After commenting on Ichigo's incompetence in dealing with them, makes a cryptic comment about having a job to do and we cut over to Hueco Mundo. There, we see that Aizen's amusing himself by messing with Orihime and Luppi, who's somewhat annoyed that he nearly died just so Ulquiorra could kidnap some girl in a needlessly elaborate way. But it's all good, since Aizen apparently expected better of him. Orihime in then ordered to heal Grimmjow's arm, which Luppi believes to be impossible. But clearly, it's not, as the arm is restored in perfect condition. Aizen explains that her power is actually to erase things from reality, thus explaining the 'I reject' call she does for her moves. Grimmjow, now with his full power restored, has Orihime fix his tattoo. He then promptly kills the girly-man who stole his Espada spot, earning him his spot back.
Ichigo and co. run through an infinite void between places, and decide that the best way to spend their time is by needling each other. Chad brings up that Ryuuken made Ishida promise never to work with shinigami again, so he explains that since Ichigo's acting in defiance to SS's orders, working with him doesn't count as working with shinigami. He seems to be pretty proud of this loophole. We now cut over to Ryuuken, looking at his son's letter. Isshin, of all people, decides to show up and bother him. They apparently know each other, and there's another reference to Isshin only regaining his powers recently. The topic shifts to Ishida's letter, which Ryuuken has no intention of reading. He says that now that he restored his sons powers, what he does with them is up to him. They call each bad parents, and we're back to Orihime, whose angsting is interrupted by the heroes' arrival in Hueco Mundo. They see a weird silhouette approaching them, and the chapter ends.
Grimmjow sure got some good regeneration in, didn't he? And Ryuuken, and in silver, lighting up a cigarette. But now. Orihime gives Grimmjow a way to break out of the mental vice, or so he thinks. Really, with his competitive nature, shutting down Luppi was a pretty predictable thing for him to do, and with him returned to full power, he'll be more determined than ever to settle things with Ichigo. Which is, of course, exactly how Aizen wants it. And it's not like it cost him anything significant; just one disposable Arrancar. Well, six disposable Arrancar, counting Grimmjow's fraccion. Makes you wonder why Aizen's trying to get Grimmjow to focus on Ichigo, doesn't it? And Orihime. Never has the old dilemma about healing injured solders been more direct. Her healing Grimmjow directly lead to Luppi's grisly death, and even though they were enemies and it's a net win for her side, that bothers her. Lastly, Ryuuken and Isshin. Ryuuken claims he doesn't care, but why bother extracting that promise out of him in the first place if that was it? He's just like his son, really; too busy being aloof and uncaring to notice that his actions totally show how much he cares. And there's an unmistakable resemblances between the Kurosaki's as well; they both hide everything from the people close to them, even when sharing the information would be helpful.
